Aphis sedi Kalt. 



The Garden Orpine, or Live-for-ever, Seduni purpureum 

 Tausch., along the Orono roadsides was observed to be badly de- 

 formed in June, the stem terminating in a rosette of abnormally- 

 small leaves (Fig. 3). The aphid concerned with this deforma- 

 tion corresponded to ApJiis sedi Kalt as presented both by Koch 

 and Buckton and there seems no reason to consider it a different 

 species. This species has not previously been recorded for 

 America. (Aphid 24-10). 



Biicalliptcrus tiliac (Linn.) 



From September 5 to 29 collections of ^. tiliae were made 

 from the ventral surface of leaves of the basswood. Tilia ameri- 

 cana L. at Orono. During this month, apterous viviparous, alate 

 viviparous, apterous oviparous females and alate males were 

 taken. (Aphid 1 10-10). 



Pemphigus rhois (Fitch). 



Sumacs in Bangor, Me., were rendered particularly ornamen- 

 tal this fall by virtue of great numbers of the large beautiful 

 galls of P. rhois on the leaves. The aphids in one gall were 

 counted on October 2, and 141 apterous viviparous forms, 1150 

 winged viviparous forms besides numerous nymphs and pupae 

 were present in a single gall. (Aphid 145-10).
